Tianji 8 100 and Tianji 9000 were designed by MediaTek. For integrated soc, the premise of chip mass production must first be integrated design. Tianyi chip now supports 5G signals, which means that 5G RF chips need to be integrated inside the chip. Huawei's Kirin is limited to manufacturing 5G RF chips.
Huawei can use Qualcomm's 4G chip because Qualcomm's soc is a product independently designed by the United States, and the RF chip in it is also an intellectual property right of the United States. Although the United States has imposed sanctions on Huawei, American companies do not agree with this practice.
After the United States issued a ban on Huawei, Qualcomm held talks with the government to the effect that if the United States does not allow Huawei to independently develop chips, it will not restrict Huawei's development, but it may hand over billions of dollars of market to other competitors in Qualcomm.
It is reported that after Huawei was sanctioned, it also signed purchase letters with Qualcomm and MediaTek. MediaTek's soc itself has a very high market share in the low-end price range. If Huawei's market share is added, on the whole, MediaTek's product share will reach two-thirds in the future, far exceeding that of Qualcomm.
In the past, MediaTek Tianji was mostly equipped with low-end products, and there were almost no high-end products. In Snapdragon, soc was the main product. Now, MediaTek has released the Tianji 9000 based on arm v9 architecture and TSMC 4nm process. This chip was first introduced in OPPO's find x5 series, which is also the first time that MediaTek's chip has been applied to high-end models.
Moreover, this soc has obvious advantages compared with Snapdragon 8 which is also based on arm v9 architecture and Samsung 4nm technology.
This also proves that Qualcomm's original idea is correct. If Huawei and MediaTek release, Qualcomm's market share is likely to be surpassed by MediaTek.
As for why Huawei doesn't purchase MediaTek's 8 100 and 9000 now, on the one hand, these two new SoCs need a long time to run in, especially Huawei's imaging algorithm, which needs a lot of time to try and optimize. Moreover, the overall soc design in MediaTek is not as good as that in Qualcomm, and it is easy to roll over.
On the other hand, MediaTek's 5G RF front-end is still American technology, so it is difficult to purchase. The Snapdragon in Qualcomm itself is a native of the United States. Huawei's adoption of Qualcomm's soc can also be seen as increasing Qualcomm's market share and contributing to American semiconductor technology and its share in the industry. From all aspects, it is the safest choice for Huawei to adopt Qualcomm's soc now. Can only choose to live first, and then think of a way to break the game.
